Answer 1

Ok thanks to all I just need to set memory_limit = 94G in dompdf class and now it is creating large pdf but after some minutes browser says "The connection was reset - The connection to the server was reset while the page was loading. etc...." although I increase the execution time up to 3600 sec //ini_set('max_execution_time', 3600)
